Introduced by U.S. Sens. Michael Enzi (R-WY) and Tim Johnson (D-SD), the bill acknowledges efforts of Native Americans, bison producers, conservationists, sportsmen, educators and other partners to recognize bison for their cultural, economical and ecological significance across the American landscape. Sens. Enzi and Johnson introduced the legislation at the request of a coalition of bison producers, tribal representatives and conservationists that plan to celebrate the first Thursday of each November as National Bison Day.
